Lenses can bend light and sound in almost any direction
PhysOrg    Share    Share on FacebookTwitterShare on LinkedinE-mail article
When an optical fiber is bent by 90 degrees or more, the light begins to leak away, posing a problem for fiber optics communications. But by using special lenses that can bend light by not only 90 degrees, but also 180 degrees (i.e., a U-turn) or 360 degrees (i.e., a full loop), scientists may limit light leakage in optical fibers and overcome this problem, not to mention provide a useful material for many other applications. Recently, a team of scientists has theoretically investigated materials for achieving this kind of advanced light control, which could work equally well for sound waves. More

Electrons tunnel nicely through boron nitride
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Ultrathin sheets of hexagonal boron nitride (h-BN) could make for the ideal dielectric layer in future electronic components, thanks to a high degree of uniformity in how electrons tunnel through the material. That is the claim of an international team of researchers that is studying how the material performs as a barrier layer that is sandwiched between two conducting layers. The team found that the tunnel current depends exponentially on the number of h-BN atomic layers - down to just a single-layer thickness. The result bodes well for using h-BN in electronic components such as tunnel devices and ultrafast field-effect transistors, say the researchers. More
